I purchased a 2009 FHTR Road Glide August 2, 2011. It is my dream bike and I love it. The owner's manual said the accessory switch is for owner's use and to see the dealer for uses. It also says there is an accessory connector on the battery. I do have an electric vest. Is that a possble use for accessory switch? I would appreciate any information regarding uses for the accessory switch. I do have a battery tender on the bike but the battery cable was already installed on the battery by the previous owner. Thanks guys.
